Runnin toooo rich?
 

I just noticed after i got an exhaust system into my car.. non-cat back.. just performance muffler, that my car is runnin a biiittt too rich at times like this when gas prices are sky rocketing!!!!..

Anyway to DIY fuel management? lol.. would it be good to reset the computer since some people told me it's better too whenever i put in any performance parts or whatever?? i have an intake and exhaust in my car after i got a motor swap for a JDM ZC... or would it be better if i just put the stock intake back on??

what ECU are you using for the ZC?

how do you know your car is running rich?

lemme guess.... he smells gas in his exhaust :D hahaha that's what most ppl say :haha:

I smell raw fuel from my car, yet I get 41 mpg (imperial) or 34 mpg (US measure) (6.88 liters per 100 kms)

you are not running rich now. geez even if you are do you really think its enough to cost you at the pump?

damn.. this is crazy.. i can usually run like 700k on a tank and but I'm running like 550k on a tank now cause it's too rich..

its probably b/c your driving more aggressive b/c you like the sound of your muffler. I don't see how putting a muffler on can cause your car to run rich.

how would u really know if ur running rich? and if u are does it affect u when ur getting ur emissions done?

You would have a high HC reading when doing the e-test.

bad? would it still pass?

when they do a safty / e-test do they put in ur car info like vin number etc...cuz i jsut realized somethign - my cousin bought a 89 toyota carolla and i know this guy who got some other dude to give us the safety/e-test so we didnt have to get it doen - cost us $80 but then after he was able to get insurance and stuff....
